As new innovations on the XRP Ledger continue to advance, maintaining robust security measures is critical to upholding trust and integrity throughout the ecosystem.
On October 22, the cybersecurity firm Softstack GmbH completed a comprehensive security audit of the Multi-Purpose Token (MPT) implementation on the XRP Ledger. The focus of this audit was to ensure that the MPT’s design, efficiency, and security assumptions met or exceeded industry standards. The Softstack team evaluated key aspects of the token’s functionality—from storage claims and operational performance to unidirectional trustline security.
Softstack GmbH’s audit covered five risk levels in relation to MPT functionality:
- Critical: A vulnerability that can disrupt the codebase functioning in a number of scenarios, or creates a risk that the codebase may be broken.
- High: A vulnerability that affects the desired outcome when using a codebase, or provides the opportunity to use a codebase in an unintended way.
- Medium: A vulnerability that could affect the desired outcome of executing the codebase in a specific scenario.
- Low: A vulnerability that does not have a significant impact on possible scenarios for the use of the codebase and is probably subjective.
- Informational: A vulnerability that can have informational character but is not affecting any of the codebase.
Softstack’s findings were highly encouraging. The audit revealed no critical or high-severity vulnerabilities. Instead, the assessment identified only a few low-severity and informational issues, all of which have been fixed or acknowledged. In particular, recommendations were implemented to enhance memory safety in MPT issuer handling, improve locking mechanisms to prevent race conditions, and clarify certain function behaviors.
"The safety and transparency of blockchain technology are core to Softstack’s mission, and we're pleased to have supported Ripple in advancing the security and performance of the XRP Ledger," said Yannik Heinze, CEO at Softstack.

Multi-Purpose Token (MPT) Audit Highlights
The audit team validated the token’s space and performance claims, confirming that MPT creation, transfer, locking, and destruction functioned as intended without introducing new vulnerabilities. They verified proper adherence to the relevant coding and security standards, ensuring that best practices continue to inform the MPT’s development.
No significant concerns were raised that would impact the MPT’s readiness for integration with the broader XRPL ecosystem. The resolved issues further reinforce the MPT’s operational integrity, making certain that the MPT implementation remains secure, efficient, and future-proof.
As with previous security efforts across the XRP Ledger, these steps reinforce the ecosystem’s commitment to rigorous evaluation. Ensuring the long-term reliability and resilience of innovative features, like the MPT, ultimately benefits developers, users, and stakeholders as the XRPL continues to evolve.
Important Step in Tokenized Future
Tokenization is at the heart of blockchain’s transformative potential, enabling seamless creation and transfer of value in various industries. As the digital asset economy continues to grow, security and efficiency are non-negotiable. The collaboration with Softstack GmbH ensures that MPT is ready to meet the demands of enterprise-grade tokenization while upholding the XRP Ledger’s trusted reputation.
